try extract array final string[] can access within listener.

you need equals compare strings.

final string[] values = getresources().getstringarray(r.array.routelist); listadapter routeadapter = new customadapter(this, values);  final listview routelistview = (listview) findviewbyid(r.id.routelistview); routelistview.setadapter(routeadapter);  routelistview.setonitemclicklistener(         new adapterview.onitemclicklistener() {             @override             public void onitemclick(adapterview<?> parent, view view,     int position, long id) {                  string route = values[position];                 if (route.equals("1. shark bait - 5.9")) {                      intent intent = new intent(mainactivity.this,     routedetails.class);                     intent.putextra("route", "shark bait");                     startactivity(intent);                 }
